Aiming to the problem of scalability caused by frequent route updates in current inter-domain routing system, this paper proposes a scalable inter-domain routing update mechanism to restrict the propagating scope of the update, called SIRUM. The autonomous system estimates the probability of that the communications of its neighbors are affected by the update according to the history information of...
The vehicle routing problem is a classical NP (Non-deterministic Polynomial) problem, and it is usually difficult to obtain the satisfied solution by the traditional method. On the basis of analysis of the existing genetic algorithm, the vehicle routing problems is solved through the improved mutation operator and the genetic algorithm of natural number coding scheme. Experiment result indicates that...
Multipath inter-domain routing can solve many technical flaws which have been exposed in BGP, but the market-driven factors have more direct relationship with its deployment. In order to analyze impact of these market-driven elements, this paper established an optimization model for Internet service provider (ISP) revenues based on user's utility function. Then, the solution using Lagrange multiplier...
In this study, we consider the application of a hybrid particle swarm algorithm to the grain logistics vehicle routing problem with time windows (VRPTW). VRPTW is a variant of the well-known well-studied vehicle routing problem (VRP), which the objective is to use the limited vehicles so that the maximum number of jobs can be completed with minimum cost. Aiming at the characteristics of the large...
Design of high-performance router is one of the greatest challenges facing Network-on-Chip (NoC). A 5-stage pipelining scheme was proposed for wormhole router in NoC. It originates from the canonical 4-stage pipelining scheme, and had the longest stage for virtual-channel allocation in the ancestor split into two stages. The 5-stage pipelining scheme may boost the maximum frequency of the router and...
